There’s a tremendous amount of materials development taking place now to protect and improve the performance of the modern solider. One of the materials being actively investigated isn’t new at all, however. It’s wool—the same material used by the Army of the Potomac in the 1860s. The Marine Corps temporarily banned the wearing of synthetic materials by combat troops after soldiers sustained serious burns from clothing that burned, and sometimes melted, fusing to skin. Short-term, soldiers shifted to all-aramid clothing, an expensive and uncomfortable solution. The Army Soldier Systems Center has been developing a family of woolen, flame-resistant woven and knitted fabrics to replace polyester and nylon. The American Sheep Industry Association and the American Wool Council developed two knit fabrics and one woven fabric that are flame retardant. The US Army is current considering a fabric that is a blend of 50 percent wool and 50 percent Nomex, a meta-aramid made by DuPont. Wool improves the comfort and reduces the cost. TenCate Southern Mills received a million dollar order from the US Army to provide Lenzing FR rayon, for the Defender M program in which a fabric with a camouflage print made from Lenzing FR and para-aramid or polyamide. Lenzing FR may also be paired with wool in another program under evaluation.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
Engineers trying to keep track of the ever-ballooning number of materials and machines for additive manufacturing and 3D printing now have some relief: a free searchable database with more than 350 machines and 450 different materials.
At JEC Europe Dow Automotive introduced a new ultra-fast, under-60-second molding cycle time for its commercial-grade VORAFORCE 5300 epoxy resin matrix for carbon composites. It's aimed at high-volume automotive manufacturing.
